  • Search & Data Management: Implement and optimize search capabilities using Elasticsearch and manage data across relational and non-relational stores like PostgreSQL and Redis
  • API Integration: Design, construct, and integrate RESTful API services to ensure seamless communication between the frontend UI and backend logic
  • DevOps & CI/CD: Build and maintain continuous integration and deployment pipelines, promoting best practices for automated delivery
  • Quality & Testing: Conduct comprehensive end-to-end, cross-browser, and device testing, ensuring all applications meet WCAG 2.0 (AODA) accessibility standards
  • Agile Collaboration: Participate in design sprints, contribute technical ideas, and collaborate with multidisciplinary professionals throughout the Software Development Life Cycle (SDLC)

Requirements:

  • 5+ years of hands-on experience in a professional environment implementing large-scale solutions with Drupal and Symfony
  • 3+ years of experience with JavaScript frameworks and Elasticsearch
  • Demonstrated experience with PostgreSQL (relational) and Redis (non-relational/caching) data stores
  • Strong understanding of cloud delivery models and hands-on experience with DevOps practices and CI/CD tools
  • Deep knowledge of WCAG 2.0 accessibility standards and experience running automated test scripts
  • Proven ability to work within Agile teams, participating in sprints and eliciting requirements from diverse stakeholders
  • Specialist-level knowledge in programming, analysis, and architectural design patterns
What we offer:
  • Technical Leadership: Act as the technical advisor for specific deliverables, ensuring quality control and architectural integrity across the entire stack
  • Modern Stack Exposure: Work with a sophisticated blend of enterprise PHP frameworks, cloud-native deployments, and advanced search technologies
  • Impactful Collaboration: Engage in design sprints where your technical ideas directly influence the product roadmap and user experience
